DS2438AZ+T&R

Battery Management Overview

The DS2438AZ+T&R is a smart battery monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for single-cell battery management applications. It supports Lithium-ion, Nickel Cadmium (NiCd), and Nickel Metal Hydride (NiMH) battery types. The device operates within a supply voltage range of 2.4 V to 10 V and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in an SOIC-8 surface-mount format, it integrates measurement capabilities for cell voltage, current, and temperature via a 1-Wire interface.

Battery Management Feature Summary

• Integrates high-resolution analog-to-digital converters for precise monitoring of cell voltage, current, and temperature.
• Provides real-time state-of-charge tracking and remaining capacity estimation using coulomb counting algorithms.
• Features a robust 1-Wire digital interface for bidirectional communication with host microcontrollers.
• Includes programmable alarms and thresholds for over-voltage, under-voltage, and over-temperature protection.

Battery Management Applications

• Smart battery packs for portable electronics
• Medical equipment power systems
• Industrial control battery backups
• Uninterruptible power supply (UPS) modules

Battery Management Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance documentation matches specific revision requirements. Ensure packaging integrity for reel or cut-tape formats during storage. Validate lot codes against current production cycles to avoid obsolete stock risks.

Battery Management Selection Notes

Select this component when precise single-cell monitoring is required alongside digital communication needs. Consider the SOIC-8 package constraints for PCB layout density. Evaluate the 1-Wire interface compatibility with existing system controllers. Assess thermal performance requirements within the specified operating temperature range for the target environment.
